The Fuel Modification Unit is responsible for the approval of a landscape plan for structures located in the Fire Hazard Severity Zones. The process of approval consists of reviewing aspects such as structure location and type of construction, topography, slope, amount and arrangement of vegetation, and overall site settings. Our objective, through this approval plan process, is to create defensible space necessary for effective fire protection of homes in the Fire Hazard Severity Zones.

Woolsey Rebuild Information
The Fuel Modification plan consists of Zones 1 and 2. These zones are drawn as concentric circles around each structure. Zone 1 extends from the outermost edge of the structure or appendage outward to 30 feet. Zone 2 extends from the edge of Zone 1 outward 70 feet for a total distance of 100 feet. In accordance with section 325.2.2 of the Los Angeles County Fire Code, Clearance of Brush and Vegetation Growth “Extra Hazard”, it may be determined by the fire official that some sites pose an extra hazard. In such cases Fuel Modification may exceed 100 feet but not exceed 200 from structures.
